Bio 93 Midterm Review Questions with
Detailed Verified Answers
Question: Hydration shell
Ans ✅ ✅: A hydration shell refers to the sphere of water molecules surrounding
dissolved ions or polar molecules. It forms due to the attractive forces between the
water molecules and the solute particles
Question: Hydrophobic
Ans ✅ ✅: Water fearing
Hydrophobic substances are nonpolar molecules that tend to repel and not dissolve in
water.
Question: Hydrophilic
Ans ✅ ✅: Hydrophilic substances, on the other hand, are polar or ionic compounds
that have an affinity for water. They readily dissolve or mix with water, often forming
hydrogen bonds with water molecules.
Question: Buffer
Ans ✅ ✅: A buffer is a solution that resists changes in pH when an acid or base is
added to it.
Question: Carbohydrates:
Ans ✅ ✅: Carbohydrates are organic compounds of carbon, hydrogen, and oxygen.
They serve as a crucial source of energy for living organisms and play essential
structural roles in cells and tissues. Common examples include sugars, starches, and
cellulose.
Question: Lipids
, |2
Ans ✅ ✅: Lipids are a diverse group of organic compounds that are largely non-
polar and hydrophobic. They include fats, oils, waxes, and phospholipids.
Question: Proteins
Ans ✅ ✅: Proteins are complex macromolecules composed of amino acids linked
together through peptide bonds.
Question: DNA:
Ans ✅ ✅: DNA, or deoxyribonucleic acid, is a molecule that carries genetic
information in living cells. It consists of two long chains of nucleotides twisted into a
double helix.
ATGC
Question: Amino acids
Ans ✅ ✅: Amino acids are organic compounds that serve as the building blocks of
proteins.
Question: Osmosis
Ans ✅ ✅: Osmosis is the spontaneous movement of a solvent, typically water,
through a semipermeable membrane from a lower solute concentration region to a
higher solute concentration region
Question: Pick the properties of life from the options below (select all
that apply).
Ans ✅ ✅: Order
Energy processing
Regulation
Question: Which of the following statements is a true sequence about
the emergent properties theme?
